Title: Process for the reductive dehalogenation of polyhaloaromatics using calcium and methanol
Inventor: HAWARI JALAL A
IPC: A62D3/00
Filed: 1990-09-28
Abstract: A process for the reductive dehalogenation of halogenated aromatics.   The process comprises reacting halogenated  aromatics  with  sodium  or  calcium  in  the presence  of  a  lower  alcohol  selected  from  the  group comprising methanol, ethanol or isopropanol and mixtures thereof in order to convert the halogenated aromatics to hydrogenated aromatics.   The halogenated aromatics are preferably reacted with sodium in the presence of methanol under reaction conditions whereby said sodium is in molten form.    The  preferred  starting  sodium/methanol/halogen molar ratio ranges from 30-40/15-20/1.   The process is particularly useful  for  dechlorinating  polychlorinated biphenyls found in electrical transformer oil.

Title: Multi-level probe and system for measurement of physical conditions in liquid-containing tanks
Inventor: CAMPBELL ERIC
IPC: G01N29/02
Filed: 1990-10-29
Abstract: A multi-level probe for sonic range measurements utilizes a plurality of parallel reflectors that each include an opening arranged coaxially about a beam of ultrasonic energy transmitted along a reference axis from an associated transducer. The opening in each reflector permits most of the sonic energy to pass to a subsequent reflective surface, while the periphery about the opening provides echo signals for determining physical conditions in the environment through which the sonic energy has passed. A novel system is used for determining physical conditions that are a function of time differences between signals from different reflectors, calculated with a highly efficient digital signal processing algorithm.

Title: Diabetes data analysis and interpretation system
Inventor: KAHN MICHAEL G
IPC: G16H20/10
Filed: 1991-09-20
Abstract: An automated diabetes data interpretation system is provided which combines symbolic and numeric computing approaches in order to identify and highlight key clinical findings in the patient's self-recorded diabetes data. The patent data, including blood glucose levels and insulin dosage levels, recorded by a diabetic patient over a period of time by means of a glucose meter or the like, is initially downloaded into a central processing system such as a personal computer. The accepted diabetes data is subsequently processed to (a) identify insulin dosage regimens corresponding to predefined significant changes in insulin dosage which are found to be sustained for at least a predefined segment of the overall data collection period, (b) identify statistically significant changes in blood glucose levels resulting across adjacent ones of the identified insulin regimen periods, and (c) identify clinically significant changes in blood glucose levels from within the identified statistically significant glucose level changes. The results of the diabetes data processing are generated in the form of a comprehensive yet easily understandable data interpretation report highlighting the processing results, including details pertaining to the identified insulin regimens and the associated clinically significant changes in glucose levels. <IMAGE>

Title: Method and apparatus for improving output display device resolution
Inventor: EDGAR ALBERT D
IPC: G09F9/30
Filed: 1992-02-17
Abstract: METHOD AND APPARATUS FOR IMPROVING OUTPUT     DISPLAY DEVICE RESOLUTUION                          ABSTRACT      The  present  invention  achieves  an  increase  in effective resolution of color output display devices, and in the preferred embodiment to  liquid crystal display devices.  A three component color signal being used to generate a color image in conjunction with a pel pattern is modified to horizontally displace, or delay, a single color component of the color signal by substantially one half pel  relative  to  the  remaining color  components. Additionally, the pels displaying this image are offset half a pel in the opposite direction to bring the images back into alignment, but with the pel sites horizontally out of alignment.  Further, this single component can be vertically offset in a similar manner relative to the remaining color components.   The effect of this color component offset is to increase the effective resolution of the output display device, as seen by the eye, without adding  significantly  to  the  complexity  of  the  image generating apparatus.
